Fastener structure

Abstract

A fastener structure includes a head portion, rod member and fitting member. The head portion has a lateral holding portion and vertical receiving portion. The rod member has a lateral attaching portion and engaging member. The rod member is penetratingly disposed at the receiving portion to allow the attaching portion to correspond in position to the holding portion. The fitting member is penetratingly disposed at the attaching portion and the holding portion to fit the head portion and the rod member together. To couple two objects together, the head portion drives an engaging portion of the rod member, such that the engaging portion penetrates one object before being fastened to the other object. To unfasten the objects, the head portion is moved reversely to remove the engaging portion from the other object, effecting separation of the objects, so as to achieve quick coupling and easy unfastening.

What is claimed is: 
     
       1. Fastener structure, comprising:
 a head portion having a receiving portion and a holding portion; 
 a rod member having an engaging portion and an attaching portion and penetratingly disposed at the receiving portion, the attaching portion corresponding in position to the holding portion; and 
 a fitting member penetratingly disposed at the attaching portion and the holding portion, 
 the head portion and the rod member are fixed to each other and are not rotatable and movable relative to each other. 
 
     
     
       2. The fastener structure of  claim 1 , wherein the holding portion of the head portion has a recess portion for receiving an expanding portion or a stopping portion of the fitting member. 
     
     
       3. The fastener structure of  claim 1 , wherein the receiving portion of the head portion is a vertical, transverse or lateral penetrating hole or recess portion. 
     
     
       4. The fastener structure of  claim 1 , wherein the holding portion of the head portion or the attaching portion of the rod member is a lateral, vertical or transverse penetrating hole or recess portion. 
     
     
       5. The fastener structure of  claim 1 , wherein the fastener structure further comprises a body portion for use in movable fitting. 
     
     
       6. The fastener structure of  claim 5 , wherein the body portion has a fitting portion adapted to be fitted to a first object or integrally formed with the first object. 
     
     
       7. The fastener structure of  claim 6 , wherein the fitting portion is fitted to the first object by riveting, expanding, welding, fastening, adhering or soldering. 
     
     
       8. The fastener structure of  claim 5 , wherein the head portion or the body portion has a checking portion for checking and being fitted to each other or checking and being fitted to the rod member. 
     
     
       9. The fastener structure of  claim 5 , further comprising a resilient component having an end abutting against the head portion and another end abutting against the body portion, or having an end abutting against the body portion and another end abutting against the rod member or the engaging portion. 
     
     
       10. The fastener structure of  claim 5 , wherein the rod member penetrates and exits an internal hole of the body portion, such that the attaching portion penetrates and exits the body portion, wherein, after the attaching portion has been fitted to the head portion, the fitting member is insertedly disposed in the attaching portion for fitting, such that the rod member is movably fitted to the body portion. 
     
     
       11. The fastener structure of  claim 5 , wherein the body portion has a pressed portion adapted to be pressed or pushed, such that a fitting portion of the body portion presses or abuts against a first object, allowing material of the first object to enter or flow into a material storage space of the fitting portion, so as for the body portion to be fitted to the first object. 
     
     
       12. The fastener structure of  claim 11 , wherein the body portion is of greater hardness than the first object. 
     
     
       13. The fastener structure of  claim 11 , wherein the pressed portion is disposed beside the head portion, the rod member or the fitting member and is of a greater width than the head portion, the rod member or the fitting member. 
     
     
       14. The fastener structure of  claim 5 , wherein the body portion has a pressed portion adapted to be pressed or pushed, such that a fitting portion of the body portion is expanded and fitted to a first object when pressed under an applied force. 
     
     
       15. The fastener structure of  claim 14 , wherein the pressed portion is disposed beside the head portion, the rod member or the fitting member and is of a greater width than the head portion, the rod member or the fitting member. 
     
     
       16. The fastener structure of  claim 5 , wherein the head portion or the body portion of the fastener structure has a weldable surface weldable to a weldable surface of the first object. 
     
     
       17. The fastener structure of  claim 5 , wherein solder portions are disposed between the body portion and the first object and adapted to be heated to change to a liquid state and then cooled to change to a solid state, such that the body portion and the first object are fitted to each other. 
     
     
       18. The fastener structure of  claim 5 , further comprising a torsion spring having an end blocked at the head portion and another end blocked at the body portion, or having an end blocked at the body portion and another end blocked at the rod member, such that the head portion or the rod member rotates to and fro because of resilience of the torsion spring. 
     
     
       19. The fastener structure of  claim 1 , wherein the fastener structure is disposed in a carrier, taken out of the carrier with a tool, compared with a comparison device, and precisely placed on a first object for fitting. 
     
     
       20. The fastener structure of  claim 19 , wherein the tool is a vacuum suction device or a clamp, and the first object is a PCB, a metal board or a plastic board. 
     
     
       21. The fastener structure of  claim 19 , wherein the tool is a vacuum suction device, and the head portion is an airtight structure disposed above the rod member, such that the fastener structure is attracted to the vacuum suction device by suction. 
     
     
       22. The fastener structure of  claim 1 , wherein the head portion has a tool control portion comprising the rod member and the fitting member. 
     
     
       23. The fastener structure of  claim 22 , wherein the tool control portion is a space within the head portion and disposed on two sides of the fitting member.
